Abstract

PURPOSE:To efficiently perform rice polishing to obtain polished rice of high quality by incorporating a coarse particle grinding wheel in an upper part and a dense particle grinding wheel in a lower part. CONSTITUTION:A coarse grain grinding wheel 3 is incorporated in an upper part and dense grin grinding wheels 2, 1 are incorporated in a lower part. For example, grinding wheels of a dense particle (particle size: 80 mesh) are incorporated in the lower and middle stages 1, 2 of a three-stage stacked polishing rotor and a grinding wheel of a coarse particle (particle size: 60 mesh) is incorporated in the upper stage 3 of the roller. By this rice polishing apparatus, polished rice (polishing degree: about 60-30%) of high quality can be efficiently obtained.

Description

[Detailed Description of the Invention] <<Icheon field of R industry>> This invention relates to a milling trochanter in a rigid topless rice brewing machine. (Conventional technology The polishing trochanter in rice milling equipment for IIIyR uses a grinding wheel I1 white trochanter built into a rotatable main shaft in a rigid cylindrical chamber. For example, Japanese Patent Publication No. 28-4012 The official gazette discloses a multi-stage white trochanter, and 11 Publication No. 128152/1983 lists various shapes of conventionally used trochanters. The grain size of the grinding wheel is the same from top to bottom. 《Problems to be solved by the invention》 A grinding wheel using only IIK grains for the polishing trochanter is
Refining progresses quickly in the early stages of milling, but is slow when it becomes highly polished. In addition, products using only dense-grained grinding wheels can be ground well when polished to a high level, but in the early stages of milling, the grinding efficiency is poor and there is a problem of uneven whiteness on the tops. In order to solve these problems, a coarse-grained grinding wheel is installed in the upper part and a dense-grained grinding wheel is installed in the lower part as a trochanter for a 1ft rice cleaning machine. (Function) In the early stages of fine rice, it is efficiently polished as soil using a grain grinding wheel, and when it becomes highly refined, it is efficiently refined using a grain grinding wheel.
0 is whitened. Also! ? liJl of Concession on top of I white transfer T
r4II whetstone. By incorporating a dense-grained grinding wheel at the bottom, the rather deep grinding scratches on the surface of the rice grains at the top are smoothed out by the dense-grained grinding wheel at the bottom. 《Effects》 When using only a dense grain grinding wheel, the grinding efficiency is poor in the early stages of fine graining, resulting in uneven whiteness (+51)!
Point II was solved by incorporating a 111-grain grinding wheel into the upper part of the N white trochanter. This has made it possible to produce high-quality highly polished rice efficiently. (Example) l. As illustrated in the drawing, a grinding wheel with a dense grain (grain size 80 mesh) is installed in the lower stage 1 and middle stage 2 of the 3-flat trochanter, and a grinding wheel a with 1 grain (grain size 60 mesh) is installed in the upper stage 3. Incorporated. This rice polishing equipment is used for highly fine white rice (M whiteness 6).
0% to 30%) with high quality and efficiency. 2. A ground trochanter with slightly dense grains (grain size 70 mesh) is installed in the lower stage 1 and middle stage of the trochanter, and T11 grain (grain size 6) is installed in the upper stage 3.
A grinding wheel of 0 mesh was incorporated. This ta rice device produces fine white rice with a whiteness of 75% to 75%, which is often used for sake brewing.
60% white rice can be made into high quality and efficient white rice.
